pentest-methodology

pentest-methodology is a skill for Claude Code from HermeticOrmus/LibreSecOps-Claude-Code. It costs 52 tokens per session (2,159 once invoked), scanned B, original, MIT.

A reference for planning and carrying out authorised penetration tests, which simulate attacks to find weaknesses. It covers the seven phases of the Penetration Testing Execution Standard and related testing guidance.

In plain words
What is it for?
Use it to organise web, API, network, cloud, and other security assessments, including rules of engagement, reconnaissance, and vulnerability testing.
Why use it?
It provides a shared structure for defining permission and scope, gathering information, testing systems, and reporting findings responsibly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

pentest-methodology scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- Privilege escalation: SUID binaries, sudo misconfiguration, kernel exploits, cron jobs, writable paths, capabilities

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Cloud metadata endpointmediumServer-side request forgery

One request to 169.254.169.254 can return temporary IAM credentials.

- Compute: Metadata service access (169.254.169.254), instance profile credentials

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Penetration Testing Methodology

Deep reference for PTES phases, OWASP Testing Guide structure, and practical testing patterns organized by technology and vulnerability class.

Knowledge Base

PTES (Penetration Testing Execution Standard)

The Penetration Testing Execution Standard defines seven phases of a penetration test:

Phase 1: Pre-engagement Interactions

  • Scope definition: IP ranges, domains, applications, exclusions
  • Rules of engagement: testing hours, communication channels, escalation procedures
  • Authorization documentation: signed statement of work, get-out-of-jail letter
  • Emergency contacts: who to call if testing causes issues
  • Legal considerations: Computer Fraud and Abuse Act compliance, data protection regulations

Phase 2: Intelligence Gathering

Passive reconnaissance (no direct interaction with target):

  • DNS records: A, AAAA, MX, TXT, CNAME, NS, SOA, SRV (dig, host, nslookup)
  • WHOIS data: registration details, nameservers, registrar
  • Search engine dorking: site:target.com filetype:pdf, inurl:admin, intitle:"index of"
  • Certificate transparency logs: crt.sh, Censys for subdomain enumeration
  • Public code repositories: GitHub, GitLab for exposed credentials, configuration, internal URLs
  • Job postings: technology stack identification
  • Social media: employee enumeration, technology hints
  • Shodan/Censys: exposed services, banners, certificates

Active reconnaissance (direct interaction, within scope):

  • Port scanning: Nmap SYN scan, version detection, OS fingerprinting, script scanning
  • Service enumeration: Banner grabbing, protocol-specific probing
  • Web application fingerprinting: Wappalyzer patterns, response headers, error pages, default files
  • Directory and file discovery: ffuf, gobuster, feroxbuster with targeted wordlists
  • Virtual host enumeration: Host header fuzzing for additional applications on shared infrastructure

Phase 3: Threat Modeling

  • Identify valuable assets within scope
  • Map trust boundaries and privilege levels
  • Identify likely attack vectors based on reconnaissance
  • Prioritize testing effort by risk and likelihood
  • Cross-reference with STRIDE or PASTA methodologies

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

pentest-methodology is a skill published in the GitHub repository HermeticOrmus/LibreSecOps-Claude-Code (4 stars, last pushed 9d ago), licensed MIT. It adds 52 tokens to every session and 2,159 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 2 findings (asks for root, cloud metadata endpoint). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
